Polar is a bear that Crash came across as a little cub, years ago on X.Treme Island during one of his adventures. He appeared to be an orphan, and followed Crash around.. which confused Crash, but they both quickly became friends and Polar helped Crash through his adventures in the Snowy X.Treme mountains, and then eventually end up living with Crash and Coco after the defeat of Dr Cortex.
How I made him-
Once again, not my character. But I modified him a lot, to make him suitable for the OB series. He grows up in this, and then later with Pura... becomes an anthro, so they can go into the future where Crash and Coco ended up, stuck...
Polar is (c) to Activision but this version of him, was made by me.
